Abstract

A pump impeller has two impeller bodies (10, 10A, 20, 20A) attached to each other. Each impeller body (10, 10A, 20, 20A) has an annular base wall (11, 11A, 21, 21A) and multiple partition protrusions (12, 12A, 22, 22A) separately formed on an inner surface of the base wall (11, 11A, 21, 21A). Multiple outlet channels (30, 30A) are respectively defined between the partition protrusions (12, 12A, 22, 22A). Each outlet channel (30, 30A) has a cross-sectional area decreasing from an inner end to an outer open end of the outlet channel (30, 30A). Thus, liquid flowing through the outlet channels (30, 30A) does not become turbulent and a working efficiency of a pump with the pump impeller is certainly improved.
